This can only be implemented server-side, RadioBOSS can't kick listeners from the server. Technically, it's possible by using the API that some servers have, but it's way too easier when the server manages this.
By the way, why 24 hour listening is bad? There are legitimate cases when a user is always connected, e.g. music for some public places like gym.
I've noticed when Voice Tracking, the envelope marker doesn't make a noticeable difference for fade outs so I can move my VT under the fade out or intro of songs. I would love an automatic DUCKING feature that would lower the music if I pull the voice track under the track.
